Normalized profile of the C i, C i^⋆, and C i^⋆⋆ lines near 1276 (top panel) and 1280 Å (bottom) at z_abs ≃ 2.418 towards J1439+1117, seen on the Lyα emission line of this quasar. Observed profiles are shown in black, while the profiles derived from fitting of the 1560 and 1656 Å transitions observed against the continuum source are displayed in green and the profiles computed towards the ELR alone (see text) in red. C i^⋆ absorption is significantly stronger towards the ELR for the three central components (at v = −10,0 and + 12 km s^-1) as well as the C i absorption in the v = −10 km s^-1 component. The velocity scale is the same as in Fig. 12.
